Pontoon bridge is fitted with hydraulic rams between the pontoon and the brdge deck and a reference system (clump weight/wire) running from the pontoon to the river bed. Pontoons are fitted with tidal turbines. Power from the turbines is used to move the rams up and down, conmpensating for the movement
of the pontoons, keeping the road level. Surplus power is sent to the national grid. Elegant. Excellent.

I had been contemplating a trampoline bridge... |

decent otherwise. You don't need a wire going to the riverbed though: extension of the road surface from the pontoon versus pontoon depth in the river, works. |

Simpler, shirley, to have GPS sensors on the bridge
to instruct the compensating rams? Or simpler still
to simply not put the river under the bridge in the
first place. |

To be honest, it doesn't actually mention a river, closest is "river bed" on line 3. |
